Action Potential : Occurs when a neuron sends information down an axon, away from the cell body.
Resting Potential : Negative charge in the inside of the cell; Positive charge outside of the cell. Diffusion and Electrical forces.
Threshold : the minimum amount of stimulous to create a action potential
Depolorization : Negative outside; Positive inside. Sodium channels open, sodium rushes in, charge becomes positive. .
Repolarization : Negative inside, Positive outside. Potasstium channels open, potassium rushes in, charge becomes negative.
All-or-none principle : action potentials are approximately equal in size and shape under normal circumstances. The size and shape of the action potential are independent of the intensity of the stimulus that initiated it.
